Debugging Spot the Difference

Solve spot the difference puzzles based on programs, practice debugging and develop an attention to detail. Spot the difference puzzles are usually done on pictures. Here we do them with code. We have scattered typical mistakes and slips through programs. Do you have the attention to detail to find them all. Check your own code as you write it and when you get compiler errors for similar mistakes. Attention to detail is an important skill for computer scientists to develop.
